I have WiiM Amp and have two passive speakers connected with speaker wires to the amp. I have two more nice old passive, wired speakers that I want to set up in another room and connect wirelessly to the Wiim Amp. Is that possible without buying another WiiM Amp? I'm a stereo neophyte and am not super concerned about top quality audio. I just want to make use of these nice speakers and expand my WiiM Amp network in my house.
